Abstract
The utility model discloses a dustproof cage valve. The dustproof cage valve comprises a valve body (1), wherein a valve cover (8) is arranged at the top of the valve body (1), a valve seat fixing cage consisting of a lower sleeve (3) and an upper sleeve (6) is arranged at the middle part of the valve body (1), a valve core (4) connected with a valve rod (20) is arranged in the valve seat fixing cage, and a U-shaped sealing ring (16) and a dustproof sheath (19) are arranged at the top of the valve cover (8). The dustproof cage valve has the beneficial effects of reasonable structural design, convenience in valve seat replacement, labor saving in valve opening/closing, good sealing and dustproof performance, and safety and reliability.
Description
Technical field
The utility model relates to modulating valve, relates in particular to a kind of dustproof cage valve.
Background technique
Traditional dustproof cage valve arrangement design comparison is simple, because U-shaped seal ring is not set, leakage phenomenon often occurs; Valve seat and valve body are monolithic construction, can not repair and replacement; Because the fluid pressure effect causes valve opening and closing comparatively to be required great effort; Because do not have the dirt-proof boot design, dust, foreign material are brought valve internal into along with the motion of valve rod easily, affect the sealability of valve, thereby affect valve event.
Summary of the invention
For the shortcoming of the existing cage valve that prevents dust, the utility model provides a kind of novel dustproof cage valve.
To achieve these goals, the utility model institute Adopts measure:
A kind of dustproof cage valve comprises valve body, and the valve body top is provided with valve gap, the valve body middle part is provided with the valve seat fixing caging that is comprised of lower sleeve and upper bush, be provided with the spool that is connected with valve rod in the valve seat fixing caging, the valve gap top is provided with U-shaped seal ring, and the valve gap top is provided with dirt-proof boot.
Offer the VE through hole on the spool.
The beneficial effects of the utility model: reasonable in design, valve seat is changed convenient, and valve opening and closing is laborsaving, and sealing and anti-dust performance are good, safe and reliable.
Description of drawings
Fig. 1 structural representation of the present utility model.
Embodiment
A kind of dustproof cage valve, comprise valve body 1, valve body 1 top is provided with valve gap 8, and valve body 1 middle part is provided with the valve seat fixing caging that is comprised of lower sleeve 3 and upper bush 6, convenient maintenance and replacement, be provided with the spool 4 that is connected with valve rod 20 in the valve seat fixing caging, offer the VE through hole on the spool 4, make valve opening and closing more steadily laborsaving, valve gap 8 tops are provided with U-shaped seal ring 16, valve gap 8 tops are provided with dirt-proof boot 19, and sealability improves greatly.The beneficial effects of the utility model: reasonable in design, valve seat is changed convenient, and valve opening and closing is laborsaving, and sealing and anti-dust performance are good, safe and reliable.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
